During the course of ten nights of observing (UT 27 April - 6 May 1996), the KPNO Mayall 4m Telescope was used to image the Hubble Deep Field in the near infrared. The IRIM camera employs a 256 x 256 Rockwell NICMOS-3 HgCdTe array, with a scale of approximately 0".6/pixel at the 4m f/15 Cassegrain focus. ... A paper on the HDF/IRIM data (observations, reductions, catalogs and basic analysis) is in preparation, titled "Near Infrared Properties of the Hubble Deep Field" by Dickinson et al. ...

The information path to prepare, perform and reduce a radioastronomical observation, using the Arcos correlator , is schematized in the figure: . The programs reside part on the computer network of the Arcetri Observatory, and part at the Medicina Radio Telescope . All programs running at Arcetri are written for a Sun workstation, and are public domain software, available upon request. Programs running at the telescope are written for a PC with DOS/Windows (or Linux).
